How should the student change the circuit to give negative values for current and
potential difference?
Answers
In a series circuit, the current is the same at each resistor. ... The voltage drop (I•R) will be the same for each resistor since the current at and the resistance of each resistor is the same. Thus the electric potential difference across any one of the bulbs will be the same as that across any one of the other bulbs.
Answer:
Given below is the answer
Explanation:
The learner can obtain the negative values for the circuit's current and potential difference by switching the circuit's current flow direction.
We can take into account the following options to determine the negative current flow and potential difference in a circuit:
When a device is charging, the current flows in a particular direction that is regarded as positive. When this happens, both the potential difference and the voltmeter reading will be positive.
The direction of current is reversed while discharging, causing current to become negative and the voltmeter reading to be negative as well. The potential difference is therefore adverse.
Altering the battery's terminals also changes the current and potential difference's direction, making them negative.
Thus, by changing the direction, the negative values of the current and potential difference are achieved.
