Calculate resistance from power and voltage
WebLearn the Power Formula. We’ve seen the formula for determining the power in an electric circuit: by multiplying the voltage in “volts” by the current in “amps” we arrive at an answer in “watts.” Let’s apply this to a circuit example: How to Use Ohm’s Law to Determine Current. In the above circuit, we know we have a battery voltage of 18 volts and a lamp …
