Two resistors of r1 = 30ω and r2 = 21ω are connected in parallel across a battery of voltage 10v. determine (a) the total current flowing through the circuit; b) current flowing through individual resistors c) voltage across each resistor.

a) 0.81 A

b) 0.33 A , 0.48 A

c) 10 Volts , 10 volts

Explanation:

= 30 Ω

= 21 Ω

= Voltage of the battery = 10 Volts

a)

Parallel combination of resistance is given as

Ω

= Total current flowing through the circuit

Total current flowing through the circuit is given as

A

b)

In parallel, Voltage remain same.

= Potential difference across R₁ = 10 Volts

= Potential difference across R₂ = 10 Volts

Current flowing through individual resistors is given as

A

A

c)

In parallel, Voltage remain same, hence

= = 10 Volts

explanation: magnetic pole, region at each end of a magnet where the external magnetic field is strongest. the south-seeking pole, or any pole similar to it, is called a south magnetic pole. unlike poles of different magnets attract each other; like poles repel each other.

your answer is c! hope this : )
