If the total resistance of the given circuit is 20 ohm's calculate the resistance of resistor X and the current flowing through the circuit ?
Answers
The current flowing through the circuit is 0.3 A
The circuit diagram is missing. However, the correct answer is -
Potential difference = 6 V (from the diagram) (Given)
Resistance = 20 Ω (Given)
Therefore,
= 1/20 = 1/(10+x) + 1/(25+75)
= 1/(10+x) = 1/20 - 1/100
= 1/(10+x) = 4/100
= 1/(10+x) = 1/25
= 10+x = 25
= x = 25-10
= x = 15
Thus, resistance of resistor X = 15 Ω
Voltage = Current × Resistance
= 6 V = Current × 20 Ω
= Current = 6/20 A
= 0.3 A
