PLEASE HELP IS URGENT
A current of 2A flows through a resistor for 30s.
(a) How many Coulombs of charge pass through in that time?
(b) Ifa total of 300J of energy are produced in that time, how many joules will be
produced when just 1C of charge passes?
(c) By referring to the definition of a volt, how great will be the p.d. in volts across the
resistor?
