Find the magnitude of the current density J3 in wire 3. The diameter of wire 3 is 1.5 mm . Express her answer in amperes per square millimeter to two significant figures.

You are watching: Find the current through the 30.0 ω resistor.

In the circuit presented in (Figure 1) , E = 31.0 V ,

*R*1 = 4.00 Ω,

*R*2 = 6.00 Ω and

*R*3 = 3.00 Ω .

Part A

What is the potential difference *V**a**b* between points *a* and *b* when the switch *S *is open?

Express your answer through the appropriate units.

Part B

What is the potential difference *V**a**b* between points *a* and *b* when the switch *S*is closed?

Express her answer v the appropriate units.

Part C

For the 4.00 Ω resistor, calculation the present through the resistor with *S* open.

Express your answer v the appropriate units.

Part D

For the 4.00 Ω resistor, calculation the existing through the resistor with *S* closed.

Express your answer with the suitable units.
