36/12= 3 3 IS THE AMOUT OF HALFLIVES
ONE HALF LIFE = 300
TWO HALF LIFE = 150
THREE HALF LIFE = 75
*Divide 600 three times
Magnetic field direction is given by right hand thumb rule.
If we put our thumb in the direction of current then curl of fingers will show the magnetic field direction around the wire.
Now here since current is going into the screen so we will put our thumb into the screen and then the curl of fingers is clockwise around it.
The magnetic field is clockwise.
So this would be the direction of magnetic field
Answer:
c.
Explanation:
they are all almost correct.
c is the only fully correct option
Answer:
41.053 A
Explanation:
given,
three phase kVA = 25-kVA
voltage = 440 Volt
current = ?
To determine three phase kVA when volts and amperes are know
three phase kVA = 1.73 x V x I
I = 32.84 A
the maximum overcurrent protection value is equal to
= 125 % of I
= 1.25 x 32.84
= 41.053 A
The answer I believe would be a sorry if I’m wrong
