Partial Question 2 1 / 2 pts Electrical resistance is a measure of the impedance of the flow of charge through a conducting medium like a copper wire. Resistance is defined as: R = where: R = resistance (carries units of 1 - "ohms"), V = voltage (carries units of V - "volts" = joule/coulomb), I = current (carries units of A - "amps" = coulomb/sec) The unit of electrical resistance (1 -"ohm") can be represented as: (select all that apply) O J/C V V/A O (J*S)/C 2 O V/(J*S)
