a. 720 A, 60 W
b. 2.4 mA, 28.8 mW
c. 60 mA, 720 mW
d. 12 A, 200 W

Answer 1

To calculate the current (I) and power (P) in a DC circuit with 12V supply and a load of 200 Ohms, use Ohm's Law and the power equation.

Step-by-step explanation:

To calculate the current (I) and power (P) in a DC circuit with 12V supply and a DC load of 200 Ohms, we can use Ohm's Law and the power equation. Ohm's Law states that V = IR, where V is the voltage, I is the current, and R is the resistance. In this case, we know the voltage (12V) and resistance (200 Ohms), so we can rearrange the equation to solve for current: I = V / R. Substituting the values, we get I = 12V / 200 Ohms = 0.06 Amps.To calculate power, we can use the equation P = IV, where P is the power, I is the current, and V is the voltage. Substituting the values, we get P = 0.06 Amps * 12V = 0.72 Watts.
