Question #118816

I have a circuit with two resistors in series then three following in parallel after that, r1 is 100 ohms r2 is 270 ohms, the resistors in parallel are 1000 ohms 1200 ohms and 2700 ohms, the supply voltage is 12v

i must calculate :

the supply current

the voltage dropped across each resistor

the current flowing through each of the parallel resistors

i must calculate :

the supply current

the voltage dropped across each resistor

the current flowing through each of the parallel resistors

Expert's answer

R_{1} = 100 Ohm; R_{4} = 1200 Ohm;

R_{2} = 270 Ohm; R_{5} = 2700 Ohm;

R_{3} = 1000 Ohm; U_{s} = 12 V.

I = ?; I_{R3} = ?; I_{R4} = ?; I_{R5} = ?; U_{R3R4R5} = ?; U_{R1} = ?; U_{R2} =?.

1. The value of the parallel combination of resistors R_{3}, R_{4}, R_{5}.

2. The value of the total resistance of the circuit.

Ohm

3. The supply current.

4. The voltage dropped R_{1}.

5. The voltage dropped R_{2}.

6. The voltage dropped R_{345}.

7. The current flowing through R_{3.}

8. The current flowing through R_{4.}

9. The current flowing through R_{5.}
