Calculate the following by using the formula for current and voltage. 1. Calculate the voltage in the following circuits: a. Current = 2A, resistance = 10 Ohms b. Current = 5A resistance = 2 Ohms c. Current = 100A, resistance = 2.3 Ohms - 2. Calculate the current in the following circuits: a. Voltage = 10V. resistance = 2 Ohms = 2 -- b. Voltage = 120V, resistance = 40 Ohms c. Voltage = 230V, resistance = 5 Ohms
