Long Story Short: There is no such thing as a lithium LR44 battery (or lithium SR44 battery). There are alkaline, silver oxide, and zinc-air 11.6 x 5.4 mm batteries, but there are no lithium 11.6 x 5.4 mm batteries. What … Continue reading →

Yes. Almost all outboards that have electric start and that were built in the last 20 years, will have either an alternator or a stater that charges the battery when the engine is running. Do outboard motors recharge batteries? Most … Continue reading →

lithium-ion batteries. Conventional lithium-ion batteries – which are currently the dominant status quo in smartphones, smartwatches, electric cars, so on and so forth – are built on liquid battery chemistry. That is, they comprise a solid cathode and anode, with … Continue reading →

Whether a labeled voltage is a rise or a drop depends on how the loop crosses its polarity labels. If the loop enters at the – label and leaves at the + label as in V_y, it is a voltage … Continue reading →

A voltage source that depends on a voltage input is generally referred to as a Voltage Controlled Voltage Source or VCVS. A voltage source that depends on a current input is referred too as a Current Controlled Voltage Source or … Continue reading →

A current source can certainly have a voltage across it. If the voltage across a current source is zero, then it is not delivering or absorbing any power. However, if the voltage across the source is not zero, then it … Continue reading →
