Questions & Step-by-Step Solutions
If the voltage across a conductor is 15 volts and the current is 3 amperes, what is the resistance?
Step 1: Identify the values given in the question. We have a voltage (V) of 15 volts and a current (I) of 3 amperes.
Step 2: Recall Ohm's Law, which states that Resistance (R) is equal to Voltage (V) divided by Current (I). The formula is R = V / I.
Step 3: Substitute the values into the formula. Replace V with 15 volts and I with 3 amperes: R = 15 V / 3 A.
Step 4: Perform the division. Calculate 15 divided by 3, which equals 5.
Step 5: Write down the result. The resistance (R) is 5 ohms (Ω).
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.
