Question

A simple electric circuit has a 24 V battery and a resistor of 60 ohms. what will be the current in the circuit?The resistance of the connecting wires is negligible.

Answer 1

Answer:

0.4 ᴀᴍᴘᴇʀᴇ

Explanation:

ɪɴ ᴛʜɪs ᴄᴀsᴇ:

ᴘᴏᴛᴇɴᴛɪᴀʟ ᴅɪғғᴇʀᴇɴᴄᴇ, ᴠ=24 ᴠᴏʟᴛs

ʀᴇsɪsᴛᴀɴᴄᴇ, ʀ=60 ᴏʜᴍs

ᴀɴᴅ, ᴄᴜʀʀᴇɴᴛ, ɪ=? (ᴛᴏ ʙᴇ ᴄᴀʟᴄᴜʟᴀᴛᴇᴅ)

ɴᴏᴡ, ᴘᴜᴛᴛɪɴɢ ᴛʜᴇsᴇ ᴠᴀʟᴜᴇs ɪɴ ᴛʜᴇ ᴏʜᴍ's ʟᴀᴡ ᴇǫᴜᴀᴛɪᴏɴ:

ᴡᴇ ɢᴇᴛ: 241 = 60

sᴏ, 6ɪ=24

ᴀɴᴅ, ɪ=24/60ᴀᴍᴘᴇʀᴇ

ɪ=0.4 ᴀᴍᴘᴇʀᴇ (ᴏʀ 0.4ᴀ)

ᴛʜᴜs, ᴛʜᴇ ᴄᴜʀʀᴇɴᴛ ғʟᴏᴡɪɴɢ ɪɴ ᴛʜᴇ ᴄɪʀᴄᴜɪᴛ ɪs 0.4 ᴀᴍᴘᴇʀᴇ.

Answer 2

Given:

• Potential difference,V = 24 Volts
• Resistance,R = 60 ohms.

To Find:

• Current,I = ?

Solution:

The Formula to find the current —

${\qquad}{\bigstar{\boxed{\sf{R = \frac{V}{ I}}}}}$

According to the question —

$\sf \implies \: 60 = \frac{24}{I} \\ \\ \sf \implies \: 60 \: I = 24 \\ \\ \sf \implies \: I = \frac{24}{60} \\ \\ \sf \implies \: I = 0.4 \: ampere$

Hence,the current will be 0.4 ampere.
