Questions & Step-by-Step Solutions
A circuit has a total voltage of 24V and a total current of 4A. What is the total resistance in the circuit? (2021)
Step 1: Identify the total voltage in the circuit, which is given as 24V.
Step 2: Identify the total current in the circuit, which is given as 4A.
Step 3: Recall Ohm's law, which states that Resistance (R) equals Voltage (V) divided by Current (I).
Step 4: Write the formula: R = V / I.
Step 5: Substitute the values into the formula: R = 24V / 4A.
Step 6: Perform the division: 24 divided by 4 equals 6.
Step 7: Conclude that the total resistance in the circuit is 6Ω.
Ohm's Law – Ohm's Law states that the current through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance of the conductor.
