How much current is produced by a voltage of 18 kV across a 15 kΩ resistance?
A. 1.2 A
B. 12 A
C. 120 mA
D. 12 mA
A. 183 Ω
B. 18.3 Ω
C. 66 Ω
D. 6.6 Ω
Red=2
Orange=3
Silver=10^-2
Tolarance=no colour=20%
R=23/100
=.23ohm
I=V/R
=50/.23
=217 ohm
the resistor code is BBROYGBVGW
BLACK = 0
BROWN = 1
RED = 2
ORANGE = 3
YELLOW = 4
GREEN = 5
BLUE = 6
VIOLET = 7
GRAY = 8
WHITE = 9
SILVER IS 10 PERCENT TOLERANCE, GOLD IS 5 PERCENT TOLERANCE
YOU HAVE 23 X 10^3 OR 23 kOHMS. E = IR, I = E/R = 50/23kOHMS = 2.17 mA(10^-3)
pls solution this question
