Three resistors are connected in parallel. If placed in a circuit with a 12-volt power supply. Determine the equivalent resistan
Ivan

(a) The equivalent resistance of three parallel resistors is (R₁R₂R₃)/(R₁R₂ + R₁R₃ + R₂R₃).

(b) The total circuit current is 12/R.eq.

(c) The voltage drop across and current in each resistor is IR₁, IR₂ and IR₃.

<h3>Equivalent resistance of three parallel resistors</h3>

The equivalent resistance of three parallel resistors is calculated as follows;

  • Let the first resistor = R₁
  • Let the second resistor = R₂
  • Let the third resistor = R₃

\frac{1}{R_{eq}} = \frac{1}{R_1} + \frac{1}{R_2} + \frac{1}{R_2}\\\\R_{eq} = \frac{R_1R_2R_3}{R_1R_2 + R_2R_3 + R_1R_3}

<h3>Total Circuit Current </h3>

The total circuit current is calculated as follows;

V = IR

I= \frac{V}{R_{eq}} = \frac{12 \ V}{R_{eq}}

<h3>Voltage drop in each resistor</h3>

Voltage drop in resistor 1 = IR₁

Voltage drop in resistor 2 = IR₂

Voltage drop in resistor 3 = IR₃
