Q: If a 120-volt voltage source is connected to a wire with 10 ohms of resistance, how much current is flowing through the wire? A: Substitute these values into the equation for current: Current = 120volts10ohms = 12 amps.
What is the current flow in a circuit with an applied voltage of 120 volts and a resistance of 80 ohms?
Calculate Amps
For a circuit with an applied voltage of 120 volts across a resistance of 80 ohms: Current(I) = 120 volts divided by 80 ohms. Current = 1.5 amperes.
What is the resistance of 120v?
For example, a 100 watt light bulb operating on 120 volts AC will have 144 ohms of resistance and will draw 0.833 Amps.
How do you calculate current in a circuit?
If the voltage (V) and resistance (R) of any circuit is given we can use the current formula to calculate the current, i.e., I = V/R (amps).
What is the resistance of a circuit with a voltage of 10 V in a current of 5 a use Ohms law to calculate the resistance?
Use Ohm’s law to calculate the resistance. The resistance of a circuit with a voltage of 10 V and current of 5 A is 2 ohms.
What is the relationship between current and voltage?
The relationship between voltage, current, and resistance is described by Ohm’s law. This equation, i = v/r, tells us that the current, i, flowing through a circuit is directly proportional to the voltage, v, and inversely proportional to the resistance, r.
What is the name for the flow of electrons in an electric circuit?
Electric current
Electric current is the flow of electrons through a complete circuit of conductors. It is used to power everything from our lights to our trains.

| 1700 watts | 14.17 amps |
| 1800 watts | 15 amps |
What is the current in a 120V circuit if the resistance is 5ω?
Explanation: 10/5= 2 Current =2 amperes.
What is the current when the voltage is 120V and the resistance is 10 ohms?
Q: If a 120-volt voltage source is connected to a wire with 10 ohms of resistance, how much current is flowing through the wire? A: Substitute these values into the equation for current: Current = 120volts10ohms = 12 amps.
How do you find current and voltage in a circuit?
Ohms Law and Power
- To find the Voltage, ( V ) [ V = I x R ] V (volts) = I (amps) x R (Ω)
- To find the Current, ( I ) [ I = V ÷ R ] I (amps) = V (volts) ÷ R (Ω)
- To find the Resistance, ( R ) [ R = V ÷ I ] R (Ω) = V (volts) ÷ I (amps)
- To find the Power (P) [ P = V x I ] P (watts) = V (volts) x I (amps)
How do you calculate power from voltage and current?
This can be approached in exactly the same way as the one above, only this time it is used for calculating power, voltage and current. The explanations here are that; Current equals Power divided by Voltage (I=P/V), Power equals Current times Voltage (P=VxI), and Voltage equals Power divided by Current (V=P/I).
How do you calculate the current flow in a series circuit?
Amperage (or Amps) in a Series Circuit
The equation V = I/R, known as Ohm’s Law, also holds true at each resistor in the circuit. The current flow throughout a series circuit is constant, which means it’s the same at each resistor.
What is the current through a 10 Ω resistor when a voltage of 5.0 V is applied across it?
What current will flow through a 10 ohm resistor with 5.0 V applied? The current is 0.5Ampere.
What is the current in a 10v circuit?
1/R = 1/20 + 1/10 +1/20 = 4/20 = 1/5 ==> R = 5 Ohm. The current through the circuit = 10 volt/5 Ohm= 2 ampere.
What is the voltage across an electrical circuit with a current of 10A and 200ω of resistance?
2. What is the voltage across an electrical circuit with a current of 10A and 200Ω of resistance? The current in an electrical system with 10A and 200Ω of resistance is 2000V.
When circuit is open current will flow?
Electric current is a flow of electric charge. But current only flows in closed paths. No current can flow if the circuit is broken, for example, when a switch is open in the circuit ,current will not flow in any part of circuit as circuit is open and there is no closed path available for charge to flow.
How does voltage affect the total current in a circuit?
The current in a circuit is directly proportional to the electric potential difference impressed across its ends and inversely proportional to the total resistance offered by the external circuit. The greater the battery voltage (i.e., electric potential difference), the greater the current.
Can current flow without a voltage source?
Voltage is the Cause, Current is the Effect
It is possible to have voltage without current, but current cannot flow without voltage.
What is current a flow of?
Current was originally defined as the flow of charges from positive to negative. Scientists later discovered that current is actually the flow of negatively charged electrons, from negative to positive.
What makes electric current flow?
a) A flow of charges or electrons through a conductor is called an electric current. The potential difference between the two ends makes the electric current flow through the wire.
