1. The current in a circuit is 1 amp. What will the current be when the voltage is increased by 50%?
2. A 10ohm resistor is connected across a 12 V battery. How much current is there through the resistor?
3. Three amperes of current are measured through a 27 ? resistor connected across a voltage source. How much voltage does the source produce?
4. How much power is dissipated by a 2.4 k resistor in series with a 12V power supply?
