Questions & Step-by-Step Solutions
If a circuit has a total resistance of 12Ω and a current of 1.5A flowing through it, what is the total voltage supplied by the battery?
Step 1: Identify the values given in the problem. We have total resistance (R) = 12Ω and current (I) = 1.5A.
Step 2: Recall Ohm's Law, which states that Voltage (V) = Current (I) * Resistance (R).
Step 3: Substitute the values into the formula: V = 1.5A * 12Ω.
Step 4: Calculate the multiplication: 1.5 * 12 = 18.
Step 5: Conclude that the total voltage supplied by the battery is 18V.
Ohm's Law – Ohm's Law states that the voltage (V) across a conductor is directly proportional to the current (I) flowing through it, with the resistance (R) being the constant of proportionality, expressed as V = I * R.
