i am not sure but c

mark it as brainliest

hope it helps

Answer 2

The current flow through resistor is 0.17 A.

(A) is correct option.

Explanation:

Given that,

The color band are

blue, green, brown and silver

According to band chart

The final band is silver, the tolerance is 10%.

We need to calculate the resistance

Using resistance chart

$R=(\text{first digit}\times10+\text{second digit})\times multiplier$

Read from left to right, the colored bands of blue, green, brown and silver

$R=(blue\times10+green)\times brown$

Put the value into the formula

$R=(6\times10+5)\times10$

$R=650\ \Omega$

We need to calculate the current

Using ohm's law

$V=IR$

$I=\dfrac{V}{R}$

Put the value into the formula

$I=\dfrac{100}{650}$

$I=0.15\ A$

It is the nearest of 0.17 A.

Hence, The current flow through resistor is 0.17 A.
