A student connects three resistors in parallel across a 12 V supply. Each branch contains one resistor and a switch, and all the switches are closed.
| Resistance in branch in Ω\OmegaΩ | Current in branch in A |
|---|---|
| 12 | |
| 24 | |
| 48 | |
| Total current from the supply |
Complete the table to show the current in each branch and the total current from the supply.
The student opens the switch in the 24 Ω branch. Predict the current from the supply. Explain your answer.
