Equivalent Resistance vs Supply Voltage
सूत्र
## Parallel Resistor Calculation Parallel resistors share the same voltage. The equivalent is always less than the smallest. ### Formula **1/R_eq = 1/R1 + 1/R2** Or: **R_eq = (R1 x R2) / (R1 + R2)** Branch currents: **I_n = V / R_n**.
हल किया गया उदाहरण
12 V supply with R1 = 100 and R2 = 200 ohms in parallel.
- 01R_eq = 1 / (1/100 + 1/200) = 66.67 ohms
- 02Total current = 12 / 66.67 = 0.18 A
- 03I_R1 = 12 / 100 = 0.12 A
- 04I_R2 = 12 / 200 = 0.06 A
अक्सर पूछे जाने वाले प्रश्न
Is parallel resistance always less than the smallest?
Yes. Additional paths always reduce total resistance.
What if both resistors are equal?
R_eq = R/2. Two identical resistors in parallel give half the individual value.
How about three in parallel?
Extend: 1/R_eq = 1/R1 + 1/R2 + 1/R3.
