Answer 1

Answer:

Ohm's law states that the electric current flowing through a conductor is directly proportional to the potential difference applied across its ends, provided the physical conditions such as temperature remains unchanged. ... A voltmeter (V) and four cells of 1.5 V each.

Hope it helps you dear

Answer 2

Answer:

why only moderators and brainly stars??

not fair...

Explanation:

Ohm's law states that the electrical current (I) flowing in an circuit is proportional to the voltage (V) and inversely proportional to the resistance (R). Therefore, if the voltage is increased, the current will increase provided the resistance of the circuit does not change.

Ohm's law does not hold good under all conditions as it is not a fundamental law of nature like Newton's laws. It is obeyed by metallic conductors only when physical conditions like temperature etc. are kept unchanged.
