Exercise 1

a) What is the current flowing through the second, and third lamp?

b) If the resistance of each of each lamp is 18,5 Ω, and the resistance of each ammeter is 1 Ω. What would be the voltage over the circuit?

Exercise 1

a) What is the voltage over each resistor?

b) What is the equivalent resistance to the three resistors in this circuit?

c) What is the current flowing through each resistor?

d) What is the total current flowing through this circuit?

Exercise 3
