Three resistors of resistant 1ohlm,2ohlm and 4ohlm are connected in series, find the equivalent resistant of the combination

Answer 1

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.
