A table lamp draws a current of 200 mA when it is connected to a 120-V source. What is the resistance of the table lamp?

600Ω

Explanation:

Voltage of source (V) = 120 Volts

Current drawn by table lamp (I) = 200mA

(Since 1 mA = 1 x 10^-3A

200mA = 200 x 10^-3A)

Resistance of table lamp (R)= ?

Then, apply the formula for ohms law

Voltage = Current x resistance

i.e V = I x R

120V = 200 x 10^-3A x R

R = 120V / 200 x 10^-3A

R = 600Ω (Ω is the symbol for ohms)

Thus, the resistance of the table lamp is 600Ω

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
