Three resistors of resistant 1ohlm,2ohlm and 4ohlm are connected in series, find the equivalent resistant of the combination
To find the equivalent resistance of the combination, we need to add up the resistances of each resistor.
R_equivalent = R1 + R2 + R3
R1 = 1 ohm, R2 = 2 ohms, and R3 = 4 ohms
R_equivalent = 1 ohm + 2 ohms + 4 ohms
R_equivalent = 7 ohms
Therefore, the equivalent resistance of the combination is 7 ohms.
