By What Percent Does the Current Through a Change When the Switch Is Closed?

Answer:

The percentage change in closing the switch the total heat dissipated per unit time is 50%. when the four resistors are connected of 2 ohms,3 ohms,4 ohms, and 9-ohm resistance and 20 V is a

The direction of the flow of current is from the power source to load. The function of load is to convert this electric energy into another form of energy while light bulbs convert electrical energy to heat energy. In a complete circuit when the switch is closed the current from the source of power will proceed through the load. In the circuit, if there is some breakage closed the switch does not transfer the current to the load. The breakage may be occurred in conducting wire or in the filament of the bulbs. While in an open circuit current does not flow in wires from one end of the source to another end. Light does not turn on because there is no flow of current.

For example:

In 1 ohm resistor, the initial current when the switch is closed is 4 Ampere. When three resistors are connected 1 ohm, 3 ohm, and 6 ohms. The total voltage applied is 12 V. the parallel resistors are 3 and 6.

The equivalent resistance is Req= 6×3/6+3 = 2ohm

The current flow through the 1-ohm resistor is 12/1+2 =4 A

When the switch closed the current flow through the circuit how much current flow depends on the resistance of resistors and voltage because the current and resistance are inversely related and current and voltage are directly related.
