The total capacitance of two 15uF capacitors connected in parallel is <em>30 μF</em> .
Density =mass/Volume
0.8=mass/60
Mass=0.8*60
Mass=48g

Answer:
The current is 0.248 A
Explanation:
Given that,
Inductor 
Resistance 
Voltage = 15 volt
Time 
We need to calculate the current
Using formula of current

Where, V = voltage
R = resistance
L = inductance
T = time
Put the value into the formula


Hence, The current is 0.248 A.
