Question

why we can produce more resistance when device connected in series​

Answer 1

Answer:

Since there is only one path for the charges to flow through, the current is the same through each resistor. (a) Three resistors connected in series to a voltage source. ... (b) The original circuit is reduced to an equivalent resistance and a voltage source.

Answer 2

Answer:

Since there is only one path for the charges to flow through, the current is the same through each resistor. The equivalent resistance of a set of resistors in a series connection is equal to the algebraic sum of the individual resistances.

(a) Three resistors connected in series to a voltage source. (b) The original circuit is reduced to an equivalent resistance and a voltage source.

the current coming from the voltage source flows through each resistor, so the current through each resistor is the same. The current through the circuit depends on the voltage supplied by the voltage source and the resistance of the resistors. For each resistor, a potential drop occurs that is equal to the loss of electric potential energy as a current travels through each resistor
