pls find the current through 10 ohm resistor.............
Answers
Answer:
0.25 ohm
Explanation:
The 10 ohm and 2 ohm resistor are in parallel, while the 5 ohm resistor is in series to both together.
Hence
Total resistance = 1 / [ 1 / 10 + 1 / 2 ] + 5
Tottal resistance = 1 / [ 6 / 10 ] + 5
Total resistance = 10 / 6 + 5
Total resistance= 5 / 3 + 5
Total resistance = 20 / 3 ohm
Total current ( I ) :
V / R
= 10 / ( 20 / 3 )
= 3 / 2 A
The two resistances are 10 / 6 ohm and 5 ohm, which are in series.
Thus, their current ( I ) is equal.
Therefore, current through 10 / 6 ohm resistor = 3 / 2 A
Potential difference ( P.D. ) of 10 / 6 ohm resistor :
I × R
= ( 3 / 2 ) × ( 10 / 6 )
= 5 / 2 V
The 10 ohm and 2 ohm resistor are in parallel.
Hence, their V is equal.
Current ( I ) through 10 ohm resistor :
V / R
= ( 5 / 2 ) / 10
= 1 / 4 ohm
= 0.25 ohm
I hope this is the answer
