Practice: Ohm's Law 1) The Ohm's law equation can be represented in three different ways, fill out the table below showing the different variations of the equation. Solving for Current Solving for Voltage Solving for Resistance 2) A device has an electrical resistance of 20.0 2. The device is connected to a variable power supply, that increases the voltage. Determine the current through the device at the different voltages. Voltage Current Voltage Current 20.0 V 100.0 V 40.0 V 120.0 V 60.0 V 5.00 V 3) A 35 2 resistor has a voltage drop of 9.00 V across it. Calculate the current through the resistor. 4) A device with resistance of 135 2 resistor has 0.50 A flowing through it. Calculate the voltage. 5) A 1.5 V battery powers a lightbulb. An ammeter measures the current through the lightbulb to be 0.21 A. Calculate the resistance of the lightbulb
