Question

What is the potential difference across ends of a conductor of resistance 200ohm if it carries a current of 4 milli ampere​

Answer 1

Given

❍ Resistance of conductor = 200Ω

❍ Current flowing = 4 milliamperes.

To find

❒ Potential difference across the conductor

Solution

Here we have ;

➜ Resistance (R) = 200Ω

➜ Current (I) = 4 mA = 4 × (1/10³) A = 0.004 Ampheres.

Now using Ohm's law :

❒ I = V/R

Where,

• I indicates Current
• V indicates Potential difference
• R indicates Resistance

Substituting values,

✎ 0.004 = V/200

✎ 0.004 × 200 = V

✎ 0.8 = V

✎ V = 0.8 volts.

Therefore, potential difference across the conductor = 0.8 Volts.

Answer 2

Explanation:

$\bf{\underline{\underline\orange{Given}}}$

■ Resistance of conductor = 200 ohm

■ current flowing = 4 mili ampere

$\bf{\underline{\underline\blue{To \: Find}}}$

■ potential difference across the conductor

$\bf{\underline{\underline\green{solution}}}$

■Here ,we have:-

➡️ Resistance (R) = 200 ohm

➡️ current (I) = 4 mili ampere = 4×(1/10³) = 0.004 Ampheres

■Now using Ohm's law

□ I = V/R

■where,,

• I indicated current
• v indicated potential resistance
• R indicated Resistance

substituting values,,,,,,

➡️0.004 = V/200

➡️0.004 × 200 = V

➡️0.8 = V

➡️ V = 0.8 volts

⁂,,potential differences across the conductor is o.8 volts....
