Questions & Step-by-Step Solutions

If a circuit has a total resistance of 10Ω and a current of 5A, what is the total voltage supplied by the battery?
  • Step 1: Identify the values given in the problem. We have a total resistance (R) of 10 ohms (Ω) and a current (I) of 5 amperes (A).
  • Step 2: Recall Ohm's Law, which states that Voltage (V) equals Current (I) multiplied by Resistance (R). The formula is V = I * R.
  • Step 3: Substitute the values into the formula. Replace I with 5A and R with 10Ω: V = 5A * 10Ω.
  • Step 4: Perform the multiplication: 5 * 10 = 50.
  • Step 5: Conclude that the total voltage (V) supplied by the battery is 50 volts (V).
  • 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.
