Current I is the rate at which charge moves through an area A, such as the cross-section of a wire
Answer:
(a): When the four resistors are connected in series the equivalent resistor value is Req= 48Ω
(b): when the four resistors are connected in parallel the equivalent resistor value is Req=3Ω
Explanation:
R=R1=R2=R3=R4= 12Ω
(a)
Req= R1+R2+R3+R4
Req= 48 Ω
(b)
Req= (1/12 * 4)⁻¹
Req= 3 Ω
The action that will cause the magnetic force to push two magnets closer together: is that of attraction which happens when opposite poles of the magnets approach.
<h3>Meaning of
magnetic force</h3>
magnetic force can be defined as the effect that is felt by magnetic objects that causes attraction and repulsion.
A magnetic force attracts two magnets when they are in opposite poles and repels them if they are in the same pole.
In conclusion, The action that will cause the magnetic force to push two magnets closer together: is that of attraction which happens when opposite poles of the magnets approach.
