Resistor

Resistor 1 with a resistance of 100 Ohms and resistor 2 with a resistance of 400 Ohms are connected side by side in the circuit. There is a voltage of 80V between the resistor terminals.
a) Draw a circuit diagram and write the entered quantities in it
b) Find the resulting resistance of the resistors.
c) Find the current I passing through the unbranched part of the circuit

Correct answer:

R =  80 Ω
I =  1 A

Step-by-step explanation:

R1=100 Ω R2=400 Ω U=80 V  I1=U/R1=80/100=45=0.8 A I2=U/R2=80/400=15=0.2 A  I=I1+I2=0.8+0.2=1 A  R=U/I=80/1=80 Ω
