12 mg = 0.012 g
12 mg = 1.2e-5 kg
75 kg = 75,000 g
Answer:
B1 = μ_o•I1/2πr
Explanation:
According to the right hand rule, we can say that the magnetic field at the second wire due to the current being carried in first wire is given by;
B1 = μ_o•I1/2πr
Where;
r is distance that separates the two wires
μ_o is a constant known as permeability of free space
I1 is current in wire 1
Weigh the negatives and positives and think if it's worth it or not
It holds kinetic and potential energy
Since this is in parallel circuit, if one bulb goes bad the brightness of the other bulbs should remain the same. The overall current did decrease but the resistance also decreased.
