Answer
## Part (a)The direct current is a current that always flows in the same direction.## Part (b)The potential difference calculation and corresponding answer would depend on the values of current (I) and resistance (R) given from the relevant electrical circuit. Note that this solution should be performed by using the appropriate practical values obtained from the given circuit diagram.
Explanation
## Step1:Part (a) is asking for what is meant by "Direct Current". To construct the correct answer, we need to refer to the definition of Direct Current, which refers to the flow of electric charge in one constant direction.## Step2: For part (b), we are seeking a calculation of the total potential difference or voltage across the battery according to the given circuit's parameters. The formula used to establish this relationship is "Ohm's Law," expressed as the following equation: ###
, Where
is the potential difference (Voltage),
is the current and
is the resistance.
