The current when the resistance is 10 ohms is 24 amps
What are variations?
Variations are simply data that change in values (i.e. not constant)
Types of variation
The types of variations are:
- Direct variation
- Inverse variation
- Joint variation
- Combine variation
From the complete question (see attachment), we have the following highlights
- The variation is an inverse variation
- When current (I) is 30 amps, the resistance (R) is 8 ohms
An inverse variation is represented as:
[tex]k = IR[/tex]
Where k represents the constant of variation.
The above equation can be rewritten as:
[tex]I_1R_1 = I_2R_2[/tex]
So, we have:
[tex]30 \times 8 = I_2R_2[/tex]
[tex]240 = I_2R_2[/tex]
When the resistance is 10 ohms, we have:
[tex]240 = I_2 \times 10[/tex]
Divide both sides by 10
[tex]24 = I_2[/tex]
Rewrite the above equation as:
[tex]I_2 = 24[/tex]
Hence, the current when the resistance is 10 ohms is 24 amps
