Question

help me with my !!!!!!test!!!!!
The current flowing through a conductor and the potential difference across its ends as per the readings of ammeter and voltmeter shown below the resistance of the current would be p.s 400 ma and 7 volt

Answer 1

Answer:

`I=400 mA=(400)/(1000)=0.40 A,

" V=7 " volts"`

According to Ohm's `=V=IR  

rArr  R=(V)/(I)=(7x10)/(4)=35/2Omega`

Explanation:

Answer 2

Answer:

The resistance of the conductor will be 20 Ω

Explanation :

From ohms law we know that resistance is the ratio of voltage to current. i.e.

Resistance = voltage/current

Voltage across the conductor = voltmeter reading = 5.8 v

Current flowing through the conductor = ammeter reading = 290 mA

= 290 x 10⁻³

= 0.29 A

Hence Resistance,

R = 5.8/0.29 = 20 Ω

Hence the resistance of the conductor will be 20 Ω
