Question

P=1000w
I=10A
V=200v f=50 Hz What is the value of L ?

Answer 1

$\green{ \: here \: is \: your \: answer}$

$\blue{ \: inductance \: ( \: l \: ) \: = \: \frac{potential \: (v) \: }{ \frac{current \: (i)}{ \: time \: (t)} }}$


$\red{ \: given \: in \: the \: question} \\ \\ \blue { \: current \: (i) \: = \: 10 \: ampere} \\ \blue{ \: potential \: (v) \: = \: 200 \: volt} \\ \blue{ \: frequency \: (f) \: = \frac{1}{time \: (t)} \: = \: 50 \: {sec}^{ - 1}}$


$\orange { \: time \: (t) = \frac{1}{50 {sec}^{ - 1}}}$

$\red { \: inductance \:(l) \: = \: \frac{200 \: volts}{10 \: ampere \: \times \: 50 \ {sec}^{ - 1} }}$


$\blue{ \: inductance \: (l) \: = \: 0.4 \: henry}$


${ \green{ { \huge{ \: answer \:}}}} \\ \red{ \: 0.4 \: henry}$

Answer 2

Answer:

${ \blue{ \: here \: is \: ur \: answer}}$

Speed = 15 m/sec

Time = 45 sec

Distance = Speed × Time

= 15m/sec × 45sec

= 675m

= 0.675km
