Answer to Question #195943 in Electric Circuits for ahmed

Question

Reading from left to right, the colored bands on a resistor are violet(7), yellow (4), brown(1), and gold(±5%). If the resistor measures 704 with an ohmmeter, it is

Answer 1

Gives

Band Color code

Violet=7

Yellow =4

Brown =1

Gold=5%

Resistance measure

$R=74\times10^1+(74\times10^1)\times5$ %

$R=74\times10^1\mp(74\times10^1)\times\frac{5} {100}$

$R=740\mp740\times\frac{5}{100}$

$R=740\mp37$

$R_{max}=777\Omega$

$R_{min}=703\Omega$
