Aseries combination of two resistors, 9.29 ω and 2.11 ω, is connected to a 12.0 v battery. calculate the equivalent resistance of the circuit. answer in units of ω.
calculate the current in the circuit. answer in units of a.
what is the potential difference across the 9.29 ω resistor?
answer in units of v.
what is the potential difference across the 2.11 ω resistor?
answer in units of v.

PART A)

Equivalent resistance in series is given as

now we have

PART B)

Here in order to find the current in the circuit we can use ohm's law

here we have

V = 12 Volts

R = 11.40 ohm

PART C)

Now for finding potential difference across 9.29 ohm resistance

PART D)

Similarly for finding potential difference across 2.11 ohm resistance

the answer would be c

the higher the current the higher the mag field around it the higher the influence on the compass
