If a circuit uses 2 amps of current with 12V applied, how much power does it dissipate?
6 watts
12 watts
24 watts
36 watts
The correct answer is: 24 watts
To determine the power dissipated in a circuit, you can use the formula that relates current, voltage, and power. The formula is: Power (P) = Voltage (V) × Current (I) In this scenario, the voltage is 12 volts and the current is 2 amps. Plugging in these values: P = 12V × 2A = 24 watts Thus, the circuit dissipates 24 watts of power. This calculation highlights the direct relationship between current and voltage in determining power consumption. The correct answer reflects this relationship accurately.
