Calculate Current, Voltage, and Resistance
Complete each of the following practice problems.
1. A 200 Ω resistor is connected to a power supply set at 8 V. Calculate the current going
through the resistor.
2. A load has 3.0 A of current flowing through it. The voltage across the load is 12.0 V.
Calculate the resistance of the load.
3. An electric hair dryer has a 60.0 Ω resistor that has 2.0 A of current going through it
when the dryer is on. Calculate the potential difference across the resistor.
