A heating coil transforms 100J of electrical energy into heat energy per second. The coil is cut into two halves and both the halves are joined together in parallel to the same source. Now the energy transformed per second will be If the current in an electric bulb drops by 1 % the power decreases [...]

Two resistances , connected in parallel across a source of negligible internal resistance, consumes four times the power that they would consume when connected in series across the same source. If one of the resistances is 10Ω the other is connected in parallel across a source of negligible internal resistance consumes four times the power [...]

When a battery sends current through a resistance R1 for time t, the heat produced in the resistor is Q. When the same battery sends current through another resistance R2 ​for time t, the heat produced in R2 ​is again Q. The internal resistance of battery is the heat produced in R2 ​is again Q. [...]
