Explanation:
According to Ohm's law, the voltage drop, V, across a resistor when a current flows through it is calculated by using the equation V=IR, where I is current in amps (A) and R is the resistance in ohms (Ω). This implies that the total resistance in a series is equal to the sum of the individual resistances.
The equivalent resistance is where the aggregate resistance connected either in parallel or series is calculated. ... Electrical resistance shows how much energy one needs when you move the charges/current through your devices. If you require lots of energy, then the resistance necessary is also high.
