2. Ideal single-phase step-down transformer U1 / U2 = 2400/120V. The machine is connected to the grid electricity with a voltage of 2.6 kV. From the sine shape at this time the steel core is  = 0.09sin314tWb.
Determine the number of loops of the primary and secondary wires

real, smaller and upside-down.   so the answer should be b.

radiation

explanation:

heat is transmitted by radiation

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.

energy stored in the capacitor= 9.72 x 10⁻⁴ j

explanation:

the energy stored in the capacitor is given by

e= 1/2 c v²

e= energy stored

c= capacitance= 1.5 µc= 1.5 x 10⁻⁶f

v= potential difference=36 v

so energy stored= e= 1/2 (1.5 x 10⁻⁶) (36)²

energy stored= 9.72 x 10⁻⁴j
