A resistor with colour coded value of 1000 ohms and + 20% tolerance can have an actual
resistance between

(A) 980 Ohm and 1020 Ohm ‏برق‎ 800 Ohmand 1000 Ohm
€) 1000 Ohm and 1200 Ohm (D) 800 Ohm and 1200 Ohm

For a carbon-composition resistor colour coded with Yellow, Violet, Orange and Silver stripes left
to right, the resistance and tolerance are

(A) 470 Ohms + 5% (B) 47Kilo Ohm + 10%
(€) 47 Mega Ohms + 5% (D) 4700 Ohms 5: 10%

Five Capacitors each of 5 UF are connected in parallel, the equivalent capacitance will be
