Ohm's low, Kirchof's current and voltage low and joule's low definition in simple words.

1. Ohm's LOW : Ohm's Law depends on the flow of the circle, the supply of the circle and the resistance in the circle. Ohm, the scientist, explained the relationship between pressure, flow, and resistance as follows:     when the temperature is constant, the current flowing through a full circle. It varies in proportion to the pressure supplied to that circle and the inverse ratio to the circle.

     Ohm's law applies only for DC circuits.
I=V/R

R=V/I

V=I/R

Explanation of the Rule : In any full circle while the physical conditions are constant, the pressure flowing through the circle increases, the pressure decreases or the flow decreases.  Likewise the opposition in the circle.  As the flow increases, the flow through the circle decreases and the flow increases as the opposition decreases.

Power : The amount of heat that a device spends when it flows through a full circle is its power, which depends on the voltage drop around the device and the current flowing through it.  Power = Voltage x Current. The unit of measurement of power is Watt.  If power is fed to a device more than capable, the device is at risk of malfunction.  P=V*R : P = I*R*I : P = I2R : P=V2/R.

2. Kirchoff's Laws:
The rules of kirchops are used to calculate current and current in a complex circuit.

1. KCL (Kirchoff's Current Law) : The sum of the flows coming to a junction point in the circle is equal to the sum of the flows passing through that junction point, ie the sum of the currents at the junction point is zero.

2) KVL (Kirchoff's  Voltage Law) : The sum of the voltage supplied against various conflicts across the board is equal to the cost of the power supplied to the board.  That is, the sum of the power supply of the circuit and the voltage drop in the circle is zero.

3. Joule's low :
Joule 's law of heating element: Jules' scientist has proved by his experiment that the heat generated by the release of an electric current from a conductor varies by.
1. The square of the current.
2. The ratio of the conductor's resistance (R) varies and the current (t) of current flowing.
