Question

calculate total resistance of the circuit and find the total current in the circuit I need solution
​

Answer 1

Answer:

If you know the total current and the voltage across the whole circuit, you can find the total resistance using Ohm's Law: R = V / I. For example, a parallel circuit has a voltage of 9 volts and total current of 3 amps. The total resistance RT = 9 volts / 3 amps = 3 Ω.

hope it helps..if so mark the brainliest

Answer 2

Answer:

We know,

$R = \frac{V}{I}$

Where R is resistance,V is voltage and I is current.

For example, If voltage of a circuit is 9 volts and total current is 3 amps.

So, resistance R $= \frac{9}{3} = 3\: ohm$

Resistance related more information:

This article discusses resistance along with its derivation and the resistance formula . Resistivity refers to the amount that an object resists or can withstand an electric current. Electric current refers to the flow of electrons. An easier way to explain resistance is to take the example of a person in a crowded market who has difficulty moving from one store to another. This situation is certainly same to an electron trying to make its way by a wire.

Resistance refers to the properties of materials that allow electrical current to flow. Resilience is definitely against the flow. In addition, the unit of resistance is ohms, denoted by the Greek capital letter omega Ω. Moreover, the resistance depends on the voltage of the particular resistor and the current flowing through it. Resistance refers to the measurement of opposition to current in a particular electrical circuit.

The electrical resistance of an object refers to the measurement of its opposition to the flow of electric current. The inverse value refers to electrical conductivity. Electrical conductivity refers to the ease with which electrical current can pass through. Furthermore, electrical resistance shares some parallels with mechanical friction. Also, resistors refer to components in electrical circuits. All materials resist current to some degree.
