Question

1. When the switch is open current flows through 60 and 100 Ohms resistors. According Kirchhoff’s voltage law the sum of the voltage drops on these resistors must be equal to the input voltage E

2. When the switch is closed, the current flowing through 60 Ohms resistor will split through the two resistors 100 and R Ohms.

3. Potential drop at 100 and R Ohms resistors must be equal since between the junction they split and the junction they join again the potential drop must be equal.

Answer #1

other than this if you want anything please put a comment

Resistors R 1 = 20 ohms, R 2 = 40 ohms, and R 3 = 60 ohms, are
all connected in series with one another.
The combination of three resisters in series is now connected in
parallel with a 240 ohm
resistor, and the resulting circuit is connected across an ideal
62.5 volt battery.
a) Find the equivalent resistance connected across the
battery.
b) Find the potential across each of the four resistors, and the
current through each.
c) Find...

1. A resistor with a resistance of 408 Ohms is connected to a 13
V battery . The current flowing through the resistor is
a) 29.4 mA
b) 4.896 A
c) 12 mA
d) 34 A
2) As you add more resistors in parallel to a circuit , the
total voltage .
a) remains the same
b) increases
c) decreases
3. A runner is approaching an ice cream truck that is double
parked . The ice cream truck is playing...
