How do you calculate the resistance
WebNov 27, 2024 · Using Equations (i) to (iv) we can write, IR = V = V 1 + V 2 + V 3. IR = IR 1 + IR 2 + IR 3. IR = I (R 1 + R 2 + R 3 ) R = R1 + R2 + R3. Therefore, when resistances are combined in series, the equivalent resistance is higher than each individual resistance. The equivalent circuit is shown in Figure.
