The Attempt at a Solution
I found the answer for part a to be 4.52 but i don't know how to get the second one.
Terminal voltage refers to the voltage at the terminals of a circuit or device. It is the potential difference between the positive and negative terminals, and is typically measured in volts (V).
EMF refers to the maximum potential difference that can be generated by a source, while terminal voltage is the actual potential difference that is present at the terminals. This means that terminal voltage may be lower than the EMF due to factors such as internal resistance.
Current flow in a circuit is determined by the voltage and resistance in the circuit, according to Ohm's law (I=V/R). The current flows from the positive terminal to the negative terminal, completing a circuit and powering any devices connected to it.
The relationship between terminal voltage and current flow is described by Ohm's law, which states that the current flow is directly proportional to the voltage and inversely proportional to the resistance. This means that as the terminal voltage increases, the current flow will also increase if the resistance remains constant.
Resistance is a key factor in determining the terminal voltage and current flow in a circuit. A higher resistance will result in a lower current flow for a given terminal voltage, while a lower resistance will allow for a higher current flow. Additionally, higher resistance can lead to a decrease in terminal voltage due to voltage drops across components in the circuit.
