Question

a) Identify the resistors which
are connected in parallel.
b) find the effective resistance
of the circuit.
c) Find the Ammeter reading
d) find the current passing through 6 ohms resistor​

Answer 1

Answer:

Resistors are in series whenever the flow of charge, called the current, must flow through devices sequentially. For example, if current flows through a person holding a screwdriver and into the Earth, then R1 in Figure 1(a) could be the resistance of the screwdriver’s shaft, R2 the resistance of its handle, R3 the person’s body resistance, and R4 the resistance of her shoes. Figure 2 shows resistors in series connected to a voltage source. It seems reasonable that the total resistance is the sum of the individual resistances, considering that the current has to pass through each resistor in sequence.
