The output of an AND gate with three inputs, A, B, and C, is HIGH when ________.
A) A = 1, B = 1, C = 0
B) A = 0, B = 0, C = 0
C) A = 1, B = 1, C = 1
D) A = 1, B = 0, C = 1

• The output of AND gate will be high only when the inputs are high. Hence A=1, B=1 and C=1
• 8 years agoHelpfull: Yes(2) No(0)
• when a,band c all will be 1 then output of tha and gate will be high
• 8 years agoHelpfull: Yes(0) No(0)
• c,inputs are high
  
• 8 years agoHelpfull: Yes(0) No(0)
• The answer is A=1, B=1 and C=1 because the output of AND gate will be high only when the inputs are high.
• 8 years agoHelpfull: Yes(0) No(0)
• ans C is correct because o/p =1 when all i/p is high..
• 8 years agoHelpfull: Yes(0) No(0)
• And means both input are true then only output will be high.
• 8 years agoHelpfull: Yes(0) No(0)
• Answer is C
  SOL:from the truth table of and, output is high only when all its inputs are high even if one input is low output is low
• 8 years agoHelpfull: Yes(0) No(0)
• option c
  because the output of AND gate high only when all inputs are high
• 8 years agoHelpfull: Yes(0) No(0)
• output of AND gate is high only when each of the gate has high input
• 8 years agoHelpfull: Yes(0) No(0)
• when all the input high
• 8 years agoHelpfull: Yes(0) No(0)
• When all inputs are high then the outputs will be high.
• 8 years agoHelpfull: Yes(0) No(0)
• a=1 ,b=1, c=1 when all inputs are high then output will be high becoz expression of AND gate is a*b*c
• 8 years agoHelpfull: Yes(0) No(0)
• c
  output=a&b&c
• 7 years agoHelpfull: Yes(0) No(0)
• C BECAUSE AND MEANS THE PRODUCT OF ALL INPUTS
• 7 years agoHelpfull: Yes(0) No(0)
• c
  Because All Input High Output Goes to high
• 7 years agoHelpfull: Yes(0) No(0)
• c if a=1 b=1 c=1 then and gate output high
• 7 years agoHelpfull: Yes(0) No(0)
• a=1,b=1,c=1
• 7 years agoHelpfull: Yes(0) No(0)
• c
  output of and gate is high only when all the inputs are high
• 6 years agoHelpfull: Yes(0) No(0)
• ans C
  AND gate performs multiply operation so when 1x1 =1 and again 1x1 =1
• 6 years agoHelpfull: Yes(0) No(0)
• option C is right because when all the inputs of AND gate are on then only it gives HIGH
• 6 years agoHelpfull: Yes(0) No(0)
• c) A=1,B=1,c=1
• 6 years agoHelpfull: Yes(0) No(0)
• Answer is C. For AND gate the output is high only when all the inputs are high .It does not provide any output even when any of the input tends to be 0
• 5 years agoHelpfull: Yes(0) No(0)
• option c is correct because
  The output of AND gate is high means all three inputs must be high
  eg: a.b = 1.1=1, so a.b.c=1.1.1=1
• 5 years agoHelpfull: Yes(0) No(0)
• optioon c,because the AND gate output high when all the inputs are high.
• 5 years agoHelpfull: Yes(0) No(0)
• option c;becoz and is high when 3 inputs are high
• 5 years agoHelpfull: Yes(0) No(0)
• Answer is A=1,B=1,C=1
• 4 years agoHelpfull: Yes(0) No(0)
• Answer:c
  And operation means multiplication .To get high output the three inputs should be high.if any one of input is low then output should be low this is condition for operation of and gate
