## You have to replace 1500 ohms resistor in radio. You have no 1500 Ω resistor but have several 1000 Ω ones which you would connect

You have to replace 1500 ohms resistor in radio. You have no 1500 Ω resistor but have several 1000 Ω ones which you would connect

1. Three in parallel
2. Three in series
3. Two in parallel
4. Two in parallel and one in series

Correct answer: 4. Two in parallel and one in series

Solution: Req = (1000 || 1000) + 1000 = 500 + 1000 = 1500 ohms
