Question
A resistor has a resistance of 100 ohms and a current
of 2 amperes passing through it. Calculate the voltage drop across the resistor.Solution
Ohm's Law states that V = I * R, where V is the voltage drop across the resistor, I is the current, and R is the resistance. Given: Resistance (R) = 100 ohms, Current (I) = 2 amperes Voltage (V) = I * R = 2 * 100 = 200 volts
