Figure 2 below shows a circuit with three batteries of different voltage connected with resistors. Determine the currents
I_(1),I_(2)
and
I_(3)
. Figure 2 Ans:
I_(1)=0.126A,I_(2)=-0.015A,I_(3)=0.142A
3. Figure 3 shows a metal rod f the shape of T of length
AB=8.0cm
and
CD-12.0cm
in a uniform magnetic field,
B=2.5T
. If the current which flow through the rod is 3.0 A , determine the magnitude of the forces exerted by each part of the rod. Ans:
F_(AB)=0.6N,F_(CD)=0N
