Two resistors R1 and R2 are connected in series in a circuit having the resultant resistance of 6 Ohms. if the value of resistance for the resistor R2 is 2 Ohms, calculate the value of resistance for the resistor R1.
Answers
Answer:
If two resistances R1 and R2 are connected in series then their total equivalent resistance is 9 Ω and if they are connected in parallel then their total equivalent resistance is 2
Explanation:
Two resistors R1 and R2 are connected in series and the effective resistance is 30 ohms. When these resistors are connected in parallel the effective resistance is 7.2 ohm When two resistors, R1 and R2, are in series, they have an equivalent resistance of 180 Ohms.The same current flows through each resistor in series. Individual resistors in series do not get the total source voltage, but divide it. The total resistance in a series circuit is equal to the sum of the individual resistances: RN(series)=R1+R2+R3+… +RN.
