Q
Q: What is the total current in a circuit with a 12V battery and three 4 ohm resistors connected in series?
Solution:
Total resistance R_total = 4 + 4 + 4 = 12 ohms. Current I = V/R_total = 12V / 12 ohms = 1A.
Steps: 6
Show Steps
Step 1: Identify the voltage of the battery, which is 12V.
Step 2: Identify the resistance of each resistor, which is 4 ohms.
Step 3: Since there are three resistors in series, add their resistances together: 4 ohms + 4 ohms + 4 ohms = 12 ohms.
Step 4: Use Ohm's Law to find the current. Ohm's Law states that Current (I) = Voltage (V) / Resistance (R).
Step 5: Substitute the values into the formula: I = 12V / 12 ohms.
Step 6: Calculate the current: 12V / 12 ohms = 1A.
