In the connection shown in the figure the switch K is open and the capacitor is uncharged. Then we close the switch and let the capacitor charge up to the maximum and open the switch again. Then (Use the following data : V0=30V,R1=10kΩ,R2=5kΩ)
When an electic current is passed through any wire, a magnetic field is produced around it . Then why an electric iron connecting cable does not attract nearby iron objects when electric current is switched on through it ?
If an electric switch is open then no current flows through the circuit.
