6. Which equation isn't correct
- R=resistivity/AL
- resistivity=RA/L
- conductivuty=GL/A
- R=(resistivity)L/A
- G=(conductivity)A/L
7. What is power?
- The rate of flow of charged particles
- The rate at which a component converts electrical energy into other engy types
- The energy per unit charge
8. current entering a junction is...
- smaller than the current exiting the junction
- the same as the current exiting the junction
- greater than the current exiting the junction
9. How do you calculate the total E.M.F in a series circuit?
