a condition or state of affairs almost beyond one's ability to deal with and requiring great effort to bear or overcome. "grappling with financial difficulties"
The answer is 52500 for 25% from 42000 = 10500 so 42000+10500=52500
Given Information:
Vdc = VF-L = 2.18x10⁶ V = 2,180,000 V
VF-L = voltage at full load
Ripple factor = r = 0.1 %
Voltage Regulation = VR = 0.05 %
Required Information:
Ripple voltage = Vr = ?
No-Load Voltage = VN-L = ?
Answer:
a. Ripple voltage = Vr = 2,180 V
b. No-Load Voltage = VN-L = 2,181,090 V
Solution:
a. Ripple Voltage Vr
The ripple factor is a measure of effectiveness of the rectification (the conversion of AC to DC) and it should be as low as possible.
The ripple factor is given by
r = Vr/Vdc
Re-arranging the formula to find ripple voltage Vr
Vr = Vdc*r
Vr = (2.18x10⁶)*0.001
Vr = 2,180 V
b. No-Load Voltage VN-L
Voltage regulation is given by
VR = (VN-L - VF-L)/VF-L
Re-arranging the formula to find the no-load voltage VN-L
VN-L = VR*VF-L + VF-L
VN-L = 0.0005*2.18x10⁶ + 2.18x10⁶
VN-L = 1090 + 2.18x10⁶
VN-L = 2,181,090 V
VN-L = 2.181x10⁶ V
Answer:
14,275= actual hours
Explanation:
Giving the following information:
The standard for a particular crane calls for 14 direct labor-hours at $16 per direct labor-hour.
During a recent period, 1,000 cranes were made.
The labor efficiency variance was $4,400 Unfavorable.
To determine the actual hours worked, we need to use the direct labor efficiency variance formula:
Direct labor time (efficiency) variance= (Standard Quantity - Actual Quantity)*standard rate
-4,400= (14*1,000 - actual hours)*16
-4,400= 224,000 - 16actual hours
228,400/16= actual hours
14,275= actual hours
