Q
Q: A circuit has a total resistance of 8Ω and a current of 4A. What is the voltage across the circuit? (2021)
Solution:
Using Ohm's law, V = I * R = 4A * 8Ω = 32V.
Steps: 5
Show Steps
Step 1: Identify the values given in the problem. We have a total resistance (R) of 8 ohms (Ω) and a current (I) of 4 amperes (A).
Step 2: Recall Ohm's law, which states that Voltage (V) = Current (I) * Resistance (R).
Step 3: Substitute the values into the formula: V = 4A * 8Ω.
Step 4: Calculate the multiplication: 4 * 8 = 32.
Step 5: Conclude that the voltage across the circuit is 32 volts (V).
