Questions and Answers

What equation can be used to calculate power consumption in a circuit?

Power = Current * Resistance

Power = Current squared * Resistance

Power = Voltage / Current

Power = Voltage squared / Resistance (correct)

How is power consumption related to the heat generated in a circuit?

Power consumption causes voltage drop

Power consumption leads to energy conversion into heat (correct)

Power consumption results in light emission

Power consumption increases current flow

What happens to the energy lost by electrons in a circuit?

It is converted into light energy

It is dissipated as heat (correct)

It is transformed into mechanical energy

It is stored as potential energy
