Volt can be defined as the electric potential difference between two points in an electric circuit that dissipates one joule of energy per coulomb of charge that passes through the electric circuit. Mathematically, it can be expressed as, Hence, volt can be expressed in terms of SI base units...
Now substituting Ohm’s law into the above equation we get, Thus, the current is the square root of the ratio of power and resistance. Mathematically, the formula for this is equal to: Example As shown in the below circuit, determine the current taken by , lamp. Solution: Given Data: ...
