7. Name and state the law which relates the current in a conductor to the potential difference across its ends. Draw a circuit diagram to establish the relationship between the potential difference across the two ends of a resistor and the current flowing through it.
8. Balance the following equation.
HNO3 + Ca(OH)2 Ca(NO3)2 + H2O
9. Give an example of a combination reaction.
Dear student,
Q7
It is the Ohm's law which establishes relation between current and Voltage.
The potential difference (voltage) across an ideal conductor is proportional to the current through it. The constant of proportionality is called the "resistance", R. Ohm's Law is given by: V = I R where V is the potential difference between two points which include a resistance R.
The circuit diagram is
