Ohms Law Practice Problems Worksheet - Free Printable

Absolutely! Let's solve each of these Ohm’s Law practice problems step by step.

Ohm’s Law Formula:
> V = I × R

Where:
- V = Voltage (in volts, V)
- I = Current (in amperes, A)
- R = Resistance (in ohms, Ω)

We can rearrange the formula as needed:
- I = V / R
- R = V / I

Problem 1:

> What is the voltage if a resistance of 25 Ω produces a current of 250 amperes?

Given:
- R = 25 Ω
- I = 250 A

Use: V = I × R
→ V = 250 A × 25 Ω
→ V = 6,250 V

✔ Answer: 6,250 volts

Problem 2:

> What is the current produced by a voltage of 240 V through a resistance of 0.2 Ω?

Given:
- V = 240 V
- R = 0.2 Ω

Use: I = V / R
→ I = 240 V / 0.2 Ω
→ I = 1,200 A

✔ Answer: 1,200 amperes

---

Problem 3:

> What voltage is necessary to produce a current of 200 amperes through a resistance of 100 Ω?

Given:
- I = 200 A
- R = 100 Ω

Use: V = I × R
→ V = 200 A × 100 Ω
→ V = 20,000 V

✔ Answer: 20,000 volts

---

Problem 4:

> What resistance would produce a current of 120 amps from a 6-V battery?

Given:
- V = 6 V
- I = 120 A

Use: R = V / I
→ R = 6 V / 120 A
→ R = 0.05 Ω

✔ Answer: 0.05 ohms

---

Problem 5:

> What is the current produced by a 9-V battery flowing through a resistance of 200 Ω?

Given:
- V = 9 V
- R = 200 Ω

Use: I = V / R
→ I = 9 V / 200 Ω
→ I = 0.045 A

✔ Answer: 0.045 amperes (or 45 mA)

---

Problem 6:

> What voltage produces a current of 500 amps with a resistance of 50 Ω?

Given:
- I = 500 A
- R = 50 Ω

Use: V = I × R
→ V = 500 A × 50 Ω
→ V = 25,000 V

✔ Answer: 25,000 volts

---

Problem 7:

> What resistance would produce a current of 200 amps with a voltage of 2,000 V?

Given:
- V = 2,000 V
- I = 200 A

Use: R = V / I
→ R = 2,000 V / 200 A
→ R = 10 Ω

✔ Answer: 10 ohms

---

Problem 8:

> What is the current produced with a 9-V battery through a resistance of 100 Ω?

Given:
- V = 9 V
- R = 100 Ω

Use: I = V / R
→ I = 9 V / 100 Ω
→ I = 0.09 A

✔ Answer: 0.09 amperes (or 90 mA)

---

## ✔ Final Answers Summary:

1. 6,250 V
2. 1,200 A
3. 20,000 V
4. 0.05 Ω
5. 0.045 A
