# Ohm's Law Worksheet This is a worksheet with questions related to Ohm's Law. **Ohm's Law:** * V = I × R * I = V ÷ R * R = V ÷ I **Units:** (Note: units are mentioned alongside the context of each problem) **Questions:** 1. A light bulb has a resistance of 16 Ω. If a current of 2.4 A flows through it, calculate the voltage transferred to the bulb. 2. A coffee grinder has a resistance of 85.0 Ω. If a current of 1.41 A flows through it, calculate the voltage necessary. 3. What is the voltage drop across an electrical load with a resistance of 4.0 Ω and a current of 3.0 A flowing through it? 4. An electric toaster has a resistance of 12 Ω. What current will it draw from a 120 V supply? 5. An electric clothes dryer is connected to a 230 V source. Calculate the current it draws if it has a resistance of 9.2 Ω. 6. What is the resistance of a device in a circuit if a voltage of 110 V causes a current of 10 A? 7. A portable radio is connected to a 9.0 V battery and draws a current of 0.025 A. What is the resistance of the radio? 8. A current of 2.4 mA flows through a circuit. If the device has a resistance of 750 Ω, calculate the voltage needed. 9. A food dehydrator has a resistance of 26 Ω and uses a current of 4.60 A. Calculate the voltage drop across the device. 10. A light bulb has a resistance of 16 Ω. If a current of 2.4 A flows through it, calculate the voltage transferred to the bulb. 11. What is the electrical current that flows through a flashlight bulb if the bulb has a voltage drop of 6.0 V and a resistance of 24 Ω? 12. A 3.0 V battery sends a current of 100 mA through a light bulb. What is the electrical resistance of the bulb?
