Question

$what \: \: is \: \: \: the \: \: equivalent \: resistance \: \\ \\ in \: this \: \: circut$
​

Answer 1

—› To Find:

• Equivalent resistance

—› Given:

• The given circuit is arranged in series.
• Three resistance is given.
• R1 = 100 Ω
• R2 = 300 Ω
• R3 = 50 Ω

—› Note:

• We know that when the circuit is in series, then equivalent resistance is the algebraic sum of its resistances given.
• Equivalent resistance = R1 + R2 + R3

—› Solution:

Equivalent resistance = 100Ω + 300Ω + 50Ω

⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀ ⠀= 450 Ω (ans)

—› Extra information:

• When the circuit is in parallel, then the the equivalent resistance is the sum of the reciprocal of each resistances is given:
• 1/R = 1/R1 + 1/R2 + 1/R3...
