Answer:
Explanation:
Notice that this is a circuit with resistors R1 and R2 in parallel, connected to resistor R3 in series. It is what is called a parallel-series combination.
So we first find the equivalent resistance for the two resistors in parallel:
By knowing this, we can estimate the total current through the circuit,:
So approximately 0.17 amps
and therefore, we can estimate the voltage drop (V3) in R3 uisng Ohm's law:
So now we know that the potential drop across the parellel resistors must be:
10 V - 4.28 V = 5.72 V
and with this info, we can calculate the current through R1 using Ohm's Law:
Answer:
Current, I = 5.3 A
Explanation:
It is given that,
Radius of circular loop, r = 3 mm = 0.003 m
Magnetic field strength, B = 1.1 mT = 0.0011 T
We need to find the magnitude of the current that flows through the wire. The magnetic field for a current carrying wire is given by :
I = 5.25 A
or
I = 5.3 A
So, the magnitude of the current that flows through the wire is 5.3 A. Hence, this is the required solution.
