Determine the total voltage in a circuit when the current is 5 amps and the resistance is 45 ohms.

Explanation:
Ohm's law relates voltage, current, and resistance: V = I × R. With a current of 5 A and a resistance of 45 Ω, the total voltage is 5 × 45 = 225 V. This uses the direct relationship that volts come from multiplying current by resistance. If you got 450 V, that would require 90 Ω; 25 V would require 5 Ω; and 2250 V would require 450 Ω.
