What is the rule for equivalent resistance when resistors are connected in series?

. 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.

What are the laws of series resistors?

The total resistance of a series circuit is equal to the sum of individual resistances. Voltage applied to a series circuit is equal to the sum of the individual voltage drops. The voltage drop across a resistor in a series circuit is directly proportional to the size of the resistor.

What are the 3 laws of series circuit?

From this definition, three rules of series circuits follow: all components share the same current; resistances add to equal a larger, total resistance; and voltage drops add to equal a larger, total voltage. All of these rules find root in the definition of a series circuit.

What is the rule of equivalent resistance?

The equivalent resistance of two resistors connected in series is the sum of the individual resistances. The reciprocal of the equivalent resistance of two resistances connected in parallel is the sum of the reciprocals of the individual resistances.

What simple rule can be used to determine the equivalent resistance of two resistors in parallel?

If the two resistances or impedances in parallel are equal and of the same value, then the total or equivalent resistance, RT is equal to half the value of one resistor.

What is the equivalent resistance of series combination of three resistor?

For explanation I would say: When three resistors are connected in series, then the equivalent resistance of this combination is Rs = R1 + R2 + R3. So, if 3 resistors having resistances 10, 15, and 20 ohms, are connected in series, then equivalent resistance of this combination is Rs = 10+15+20 = 45 ohms.

What would be their equivalent resistance?

The equivalent resistance of a network is that single resistor that could replace the entire network in such a way that for a certain applied voltage V you get the same current I as you were getting for a network.

What is the resistance law for a parallel circuit?

The total resistance in a parallel circuit is always less than any of the branch resistances. As you add more and more branches to the circuit the total current will increase because Ohm’s Law states that the lower the resistance, the higher the current.
