Water is heated with a coil of resistance R connected to domestic supply. The rise of temperature of water will depend on 1. Supply voltage 2. Current passing through the coil. 3. Time for which voltage is supplied. Select the correct answer from among the following:
Options
- A1,2 and 3
- B1 and 2 only
- C1 only
- D2 and 3 only
Correct answer
A. 1,2 and 3
Step-by-step solution
