Akangkshya Bordoloi 1 year, 1 month ago

In series, Current stays the same but voltage is divided.. Overall Resistance in series is always higher than the resistance of any of its constituent resistors. Equivalent Resistance in series connection(Rs) is given by : Rs = R1 + R2 In series connection, the conductors are connected in series, sequentially. Ammeter is connected in series arrangment. In parallel, Current is divided but voltage remains same.. Overall Resistance in parallel is usually lesser or equal to the resistance of any of its constituent resistors. Equivalent Resistance in parallel connection(Rp) is given by : 1/Rp = 1/R1 + 1/R2 In parallel connection, the conductors are connected parallel to each other. Voltmeter is connected in parallel arrangement.
